A midi slip dress works over everything and under everything. The length hits mid-calf which means it reads as both casual and slightly dressed up. Slip dresses in lightweight fabric layer easily under button-downs or sweaters. They work alone in warmer months when the minimalist design feels intentional rather than unfinished. The simplicity of the silhouette means these dresses do not compete with what goes over them. They transition from casual to slightly formal depending on what you pair them with. A good slip dress in a neutral color is endlessly useful. The minimalist approach focuses all attention on drape and fit. These dresses work for different body types because the slip shape is forgiving without being shapeless. These are the midi slip dresses that work because versatility and simplicity go together.
